PROCESS FOR THE DYEING ANDPRINTING OF METAL- CONTAINING POLYOLEFIN TEXTILE MATERIALS It has been found that materials of metal-containing polyolefins, such as filaments, fibers, foils, woven and knitted fabrics, especially those of nickel-containing polypropylene, can be dyed and printed fast when they are treated with compounds of the general formula II on ll OR being attached to adjacent carbon atoms, R represents an alkyl radical with one to four carbon atoms; A and B cannot simultaneously represent radicals of the benzene sems.

The individual process according to the invention is carried out in such a manner that the compounds of the general formula (l) are applied on to the materials to be treated, particularly fibers and fabrics, from acidic, neutral or weakly alkaline suspensions, dispersions, pastes or solutions, preferably with the use of dispersing agents, emulsifiers, dyeing accelerators, thickening agents and/or levelling auxiliaries, from a dyebath, a padding liquoror by means of a printing paste. When a dyeing liquor is used, this is brought to an elevated temperature for a certain time by gradually raising the temperature in the course of the dyeing process, for example, to temperatures of about 90l40 C., preferably to temperatures of about 95l 10 C. When a padding liquor is used, the padded fabn'c is subsequently subjected to a heat treatment, if necessary,=

after an intermediate drying. When a printing paste is used, the fabric is likewise subjected to a heat treatment after printing. The heat treatment may be carried out either by hot air or by steam, at temperatures of, for example, l00l40 C. The

duration of the treatment is generally about 1 -l0 minutes.

The resistance to rubbing of the dyeings obtained can some times be improved by an alkaline after-treatement of the dyed material, or by an after-treatment with reducing agents, such as sulfites or formaldehyde/sulphite addition products in an alkaline medium, optionally with the addition of an emulsifier.

Suitable dispersing or emulsifying agents which are advantageously added to the compounds of the formula (I) to be used according to the invention are commercially available products, such as sulfite cellulose waste liquor products, condensation products of higher alcohols and ethylene oxide, soaps, polyglycol ethers of fatty acid amides, formaldehyde condensation products of aromatic sulfonic acids or mixtures of such compounds.

To produce printing pastes which contain the compounds of the formula (I) to be used according to the invention, the customary thickening agents, such as methyl cellulose, carob bean flour, crystal gurn, alginates or tragacanth can be used. The printing pastes may also contain the usual additives, such as urea, thiourea, thiodiglycol, methylated alcohols, sodiumm-nitrobenzosulphonate or aqueous emulsions of sulfonated oils.

The' dyed orprinted materials, preferably obtained from met'a'l ctSntaining polypropylene, can be after-treated in usual manner, subsequently to the dyeing or printing process, for example, by washing, brightening, decatizing or heat settmg.

The process according to the invention is preferably used for the dyeing and printing of metal-containing, preferably nickel-containing. polypropylene fiber materials. The term metal-containing polypropylene fiber materials comprises those fiber materials whieh contain the metals either as such or in the form of their salts, but preferablyin the form of chelates. Suitable metal chelates are particularly nickel chelates or nickel compounds of phenols, bis-(alkyphenol)-monosulfides, bis-(p-alkylphenol)-sulphoxides, bis-(p-alkylphenol) sulphones dithiocarbamates, o-hydroxyphenyl-benztriazoles, hydroxamic acids, and nickel dimethyl dioxime and nickel acetylacetone, at concentrations of 0.0l to 3 percent, preferably 0.1 to 2 percent. Thenickelcomplexes can be used by themselves or in admixture withother nickel complexes or nickel salts. Instead of the nickel compounds mentioned above, the polypropylene materials may also contain salts or chelates of zinc, aluminum, magnesium, cobalt, copper or chromium by themselves or in admixture with one another. Finally, the last-mentionedn etalsalts.or chelates may also be present together in the polypropylene fiber materials in admixture with the above-mentioned-salts or chelates of nickel.

The compounds of the general formula (I) .to be used according to the invention are obtained in known manner vby reacting o-hydroxyaldehydes of the benzene or naphthalene series with o-alkoxy=ca1:boxylicaeid hydrazidesof the benzene or naphthalene series.

The following o-hydroxyaldehydesmay be used; for example: Z-hydroxy-benzaldehyde, 3-methoxy-2-hydroxy-benzaldehyde, 5-,chloro-2-hydroxybenzaldehyde, 3,5-dichloro-2- hydroxybenzaldehyde, 5-.br orn0-2-hydroxybenzaldehyde, 2- hydroxy-naphthaldehyd e-( l l.-hydroxy-naphthaldehyde-(2 2-hydroxy-naphthaldehyde-(3.), 5-chloro-2-hydroxynaphthaldehyd e-(l), 6-ehloro- 2-hydroxy-naphthaldehydel -c -Z- y r ya thald y e-( I 6-. r m hydroxy-naphthaldehyde-('1 6-methyl-2 hydroxy-naphthaldehyde-( l 2-methoxy-2hydroxy-naphthaldehyde l The following o-alkoxy-earboxylic acid hydrazides may be used, for example: 2-methoxybenzoie acid hydrazide, Z-ethoxybenzoic acid hydrazide, 2-propoxybenzoic acid hydrazide, 2- n-butyloxybenzoic acid hydrazide, 2-methoxy-5-methylbenzoic acid hydrazide, 2-methoxy-4-methylbenzoic acid hydrazide, 2-methoxy-S-tertiary-butyl-benzoi c acid hydrazide, 2-methoxy-4-n-butyl benzoic acid hydrazide, 2-methoxy-5-' chloro-benzoic acid hydrazide, 2-methoxy-4-chloro-benzoic acid hydrazide, 2-methoxy-3-methyl-5-chloro-benzoic acid hydrazide, 2-methoxy-5-methyl-4-chloro-benzoic acid hydrazide, 2,3-dimethoxybenzoic acid hydrazide, 2-methoxy-3- methyl-benzoic acid hydrazide, 2,4-dimethoxybenzoic acid hydrazide, 2-methoxy-4,6dim ethylbenzoic acid'hydrazide, 2- ethoxy-S-methyl-benzoic acid hydrazide, 2- ethoxy4-methylbenzoic acid hydrazide, Z-ethoxy-S-tert.butyl-benzoic acid hydrazide, Z-ethoxy-S-chloro benzoic acid hydrazide, 2 ethoxy-3-methyl-5-chloro-benzoic acid hydrazide, Z-ethoxy- 5-methyl-4 -chloro-benzoic acid hydrazide, 2 ,3-diethox ybenzoic acid hydrazide, 2-n-butoxy5chloro benzoic acid hydrazide, l-methoxy-naphthalene-carboxylic acid-(2) hydrazide, 2-methoxy-naphthalene-carboxylic acid-( I )-hydrazide, 2-methoxy-naphthalene-carboxylic acid-( 3 )-hydrazide, lethoxy-naphthalene-carboxylic acid-(2 )-hydrazide, 2-ethoxynaphthalene-earboxylic acid I )-hydrazi de, 2-ethoxynaphthalene-carboxylic acid 3 )-hydraz ide.
